Therefore, mass of coarse aggregate (M c) per m 3 of concrete = 0.64 × 1650 = 1056 kg/m 3 Approximate air content = 2% Mass of fine aggregates The mass of coarse aggregate can be estimated using the relationship below;. Mass of fine aggregate M f = γ f [1000 – (W – C/γ + Mc/γ c + 10A)] ————- (2). Where; γ f = Specific gravity of fine aggregate …

When the concrete surface is exposed to sufficiently high temperatures, water close to the surface begins to move out of the concrete and into the atmosphere. However, the high-temperature gradient between the surface and the inside of the concrete causes vapor to enter the concrete, which can cause condensation if the temperature drops.
